Hello;

I am using Odoo version    18;

I am selling 25 units of lumber dimensions   (Length 12 ft width 3'' thickness 1')   totaling 75 Board feet.  Order sale Amount is  75*5=375 USD.

The second sale is  40 units of lumber dimensions (Length 12 ft width 3'' thickness 1') totaling 120 Board feet. Order sale Amount is 120*5 = 600 USD.

How can I do this conversion in Odoo sale Order?

Price of   1 Board Feet is $5.

Inventory is in m 3

The board foot is a unit of measurement for the volume of lumber in the United States and Canada. It equals the volume of a board that is one foot (30.5 cm) in length, one foot (30.5 cm) in width, and one inch (2.54 cm) in thickness, or exactly 2.359737216 liters.
